Description
The KS8842M is the industry’s first fully managed 2-port
switch with a non-PCI CPU interface. The KS8842 is a
proven, 4th generation, integrated Layer 2 switch that is
compliant to the IEEE 802.3u standard.
The KS8842M can also be configured as a low-latency
repeater to allow for ‘cut thru’ in latency critical Embedded
or Industrial Ethernet applications. For industrial automa-
tion applications in the repeater mode, the KS8842M runs
in half-duplex mode regardless of the application.
The KS8842M offers an extensive feature set that includes
tag/port-based VLAN, QoS priority management, MAC
filtering function, MIB counters, and CPU control/data
interfaces to effectively address both current and emerg-
ing Fast Ethernet applications.
The KS8842 contains two 10/100 transceivers with pat-
ented mixed-signal low-power technology, two media ac-
cess control (MAC) units and a direct memory access
(DMA) channel, a high-speed non-blocking switch fabric,
a dedicated 1K entry forwarding table, and an on-chip
frame buffer memory.
